Title: Improvements in or relating to railway vehicle braking systems
IPC: B60T13/46
Filed: 1926-12-24
Abstract: 285,209. Glascodine, R. T., Mc- Dermid, W. F., and Spencer, A. Dec. 24, 1926. Fluid-pressure.-A valve device for controlling the flow of air from the train-pipe to the several brake cylinders of an automatic vacuum brake apparatus in an application of the brakes in such a manner as to ensure a uniform rate of flow of air into the brake cylinders, irrespective of the excess of the pressure in the train-pipe over that in the brake cylinder as long as that excess is above a predetermined value, comprises a piston 8 subject on its under face to the pressure in the brake cylinder connected at 5 and on its upper face to the pressure in a chamber 1<c> connected to the train-pipe through the chamber 1<b> and a conical-opening 2. The stem 11 of the piston is slidable upon a tubular member 9, which normally rests upon the bottom of the casing, against. the action of a spring 16 disposed between a shoulder 15 on the member 9 and a collar 14 secured within the stem of the piston : Holes 17 through the piston form a restricted fairway for the passage of air to the brake cylinder. When the piston is moved to its extreme upper position by the rarefaction of the air in the train-pipe as when the brake is released, it is in line with holes or recesses 18 formed in the liner 4 which then provide free communication between the train-pipe and the brake cylinders. If during an application of the brake, the pressure in the chamber 1<c> above the piston exceeds that in the chamber 1<a> and the brake cylinder sufficiently to overcome the spring 16, a shoulder 12 on the piston stem is moved downwardly to restrict more or less the opening 2 thus maintaining a constant pressure difference between these chambers and a constant rate of flow of air to the brake cylinder. The pressure in the brake cylinders near the point of control is thus prevented from building up more rapidly than in those that are more remote.

Filed: 1971-07-13
Abstract: 1354146 Mixing extruder STERLING EXTRUDER CORP 13 July 1971 [3 Sept 1970 26 Oct 1970] 32693/71 Heading B5A [Also in Division B1] Mixing apparatus for plastics materials has a coaxial rotor 1 and stator 2 with respective external and internal opposite screw threads 8, 9 including at least one "extensive" mixing section (with narrow lands and wide grooves in which the emphasis is on dispersal rather than shear coating) the depth of the opposite grooves varying at least once, the one from a minimum to a maximum and the other from a co-operating maximum to a minimum, the total depth of the two opposed grooves becoming progressively smaller towards the discharge end as indicated by the extension lines 18, 19. As shown there is a "charging" section, six "extensive" mixing sections with an intermediate venting section, and a final "intensive" mixing section 11, with lands wider than the grooves, where primarily shear working takes place. There are zone controlled heaters and cooling coils 14, 15 and the rotor has cooling channels 13. Extensive mixing.-In the charging section the stator is smooth and the rotor preferably has a single start thread of one diameter pitch. In Stage I both rotor and stator have a two-start thread, that of the rotor being of the same pitch as in the charging section. In Stage II the rotor has a single or double start thread of reduced pitch, the stator retaining a two-start thread. In Stage III the rotor has the same thread as in Stage II while the stator charges to a single start. In Stage IV the roror pitch is increased while that of the stator remains unchanged. Melting is completed in these first few stages and the material may then pass to a stage where it is vented to atmosphere or by a pump 12, the rotor groove depth being a maximum and the stator smooth. Stages V and VI follow. The relative depth of opposite stator and rotor grooves varies in each stage but the thread interface lies throughout on a cylinder 17. The material is cooled before entering an intensive mixing section which is tapered and may have a groove depth which varies twice between a minimum and a maximum in both rotor and stator, or they may both have smooth surfaces. The clearance in this section may be altered by axial adjustment of the rotor. There may be an extension die 10. The stator may be made up of separable portions corresponding to the respective stages.
